l SDECI'FIGAT'IONL To ALL wHoM 1r VMAY coNcERN:

Be it `known that I, LUTHER R. FAUGHT, of Philadelphia, in the county of Philadelphia, and StateQof Pennsylvania, have invented anew and useful Improvement inLathes; and I do hereby declare that the follow` l ing is a full, clear, and exact description thereof, which will'enable 'others skilled inthe' art to make and use the` s'ame, reference being had `tothe accompanying drawings, 4formignglpart of thisspeciicatiomin whichi l Figure 1 is a vertical longitudinal section of a portion of a lathe sho-wing'iny improvement,'taken through y the line :c 1v, iig. 2.

Figure 2 is a vertical cross-section of the sam Similar letters of reference indicate like parts, n My invention has for itsobject to `furnish an improved means for tightening the spindle in lathe-'stocks e, takenfthrough the line j/fy, lig, 1.

and it consists of the combination of a. nut and sleeve, constructed and arranged asihreinafter more fully i described,` with the spindle and stock of a lathe.

A is the tail-stock of a latheB is the end of the feed-scre\v, and C is the spindle. l D is a sleeve, the forward i end of which is cone-shaped to fit into a cone-shaped hole in ithe stock A, as shown in ig.`1. `The rear end of the sleeve D is straight, and has a coarse screw-threadcut upon it, as shown. The `sleeve is; slotted itsivhole length, and the thicker or cone-shaped part `is grooved longitudinally to giveit suiiicient spring to close ,around l the spindle C, when drawn further into the 4cone-shaped hole in the stock A,i'n'I thefmanncrhereinafter described. E is a circular nut, which is tted so nicely into a notch formed inlthe` stock A for its reception, that it may bear upon both sides of said notch, and yet be so loose as to be` readily turned by the `liand'l'e FJ This handle is screwed into a hole formed` the nut E, as shown. Other holesare` formed in the nut, so that the handle E may be shifted as desired for operating the nut E. onto compensate for the wear of the parts. A` screw-thread is formed'in the nut E, which ts upon the screw-thread forme'd upon the sleeve D. Upon` the spindle C is formed a feather, c', which Aiits into thesloti'ormed in the `sleeve' D, and when `the sleeve `isidravrnl in by' the action of the nut E, the sleeve, spindle, and nut are clamped rmly `together. By `this arrangement the wear of the parts does not interfere withholding the work with steadiness, so as to size and finish it with accuracy.

What I claim as new, and desire to-secure `by Letters Patent, is

An improved binder for lathe-spindles, formed by combining the nut E, and sleeve "D, constructed and j arranged as herein described, -wth each other, and with the spindleC, and stock A, substantially as described,

and forthe purpose set forth. ,V
